D3 will feature a second collapse but the "Veil" are just after the Traveler. No, not to revive their dead God or whatever, but to reincorporate the Material Realms back into the Void where they belong. Before the Traveler's falling out with the Deep, before it stole that power, in order to practice a different path accidently creating the material realms. In D3 they successfully recapture it, retake it, but not before the Traveler separates itself from itself and hides within you. A tiny spark, a spirit but just enough. A massive gamble, a final stand off between Light & Dark. The newly captured Dark Traveler, capable of creating Guardian-like entities, reconstructing the physical forms for the Long Forgotten Spectral Amalgamates known as the "Veil".. All known enemies from the past now join our cause to keep our way of existence, because if we were to lose. Everything would fall into Nothing. Even Hive. If you want to know what Nothing looks (feels) like. Close your left eye. Now, try to look through your left eye. You don't see black do you? Your sense of sight from your left eye is just gone while your right remains open. .. Anyway, with that in mind. You, your, us Guardians become the Needle. Without the Traveler on our side anymore, sacrificing it's true self to grant us individual ascendance we become our own seperate entities creating our own Destiny. Making the future truly ours to do as we see fit of the world that was never meant to exist.
